Chapter 210 The last line of defense
After a group of zombies set up the giant cannon, the two zombies behind them walked over carrying a huge cannonball, which was nearly ten meters long.

Han Yuan stared in a daze for a while. The shape of this cannonball looked very similar to the missiles on the earth.

A group of people in the war room looked at each other in blank dismay. This kind of weapon that fires cannonballs has been eliminated for many years, but they don't know how the zombies came out.

Could it be that a zombie with high IQ and knowledge of research appeared again among the zombies?This giant cannon was created by that zombie.

Weapons that fire cannonballs like this have weak attack power and slow speed. With today's technology, even if the attack is saturated, it can be easily intercepted without any threat at all.

I saw two zombies carrying the shells, put the bullets outwards, and put them in through the muzzle of the cannon.

After putting it in, you can still see a little pointed bullet protruding from the muzzle. After loading the shells, a group of zombies quickly retreated.

One of the zombies was holding something like a tablet computer, and what he was operating was obviously the launch controller of the cannon.

The giant cannon suddenly trembled and made a roaring sound, and there was a little red light on the fort.

There was a puff of black smoke from the muzzle, followed by a violent bang and a roar, and the huge shell was fired.

The speed of the cannonball is actually dissatisfied, it has definitely reached several times the supersonic speed, but in front of the technology of this world, it is a turtle crawling.

With the sound of howling, the shells bombarded towards the defense line. Naturally, the human side would not just sit back and watch the shells bombard them.

Even if you look down on zombie shells from the bottom of your heart, you can't let them bomb on the protective cover, which will consume the energy of the protective cover.

A beam of light was shot from within the line of defense, and the shell was intercepted ten kilometers away. The light beam bombarded the shell, causing a huge explosion.

Even if the light beam fired is not a crystal energy weapon, but an ordinary laser weapon, it can easily destroy the shells.

The power of the cannonball is not weak, but compared with the energy bomb, it is still a bit weaker. However, the volume of this cannonball is tens to hundreds of times that of the energy bomb, and the speed is much slower.

After firing a cannonball, the zombies seemed a little dissatisfied, and stepped forward to carry the cannon away.

After a while, a car drove over, stopped at the position where the cannon was parked, and raised several missile-like weapons from the truck.

Han Yuan was stunned for a while, Nima, how did these zombies test weapons?
The higher-ups of the Third Military Region also looked stunned. This kind of weapon has been eliminated for many years. How did these zombies come out?

Could it be that it was pulled out of the museum of the former human beings?

Sure enough, the zombie's weapon was launched like a missile, but it was intercepted by the defensive weapon in the line of defense.

After the violent explosion, a gray-black smoke filled the air. At the beginning, no one noticed it. It was just an outdated weapon and the smoke after the explosion.

When the zombies used this outdated weapon one after another, causing smoke and dust to fill the outside of the fifth line of defense, as well as inside the line of defense, it was only when they realized that this was not ordinary smoke, but a zombie virus!
The purpose of these zombies is definitely not that simple.

The zombie virus in the fifth line of defense suddenly became more intense. Even if human soldiers put on protective clothing and took antiviral drugs, they still had a certain risk of being infected with the zombie virus.

The fifth line of defense could not hold on for long. After discussions with the senior officials of the third military region in the combat room, they resolutely abandoned the fifth line of defense and retreated the army to the defense line of the base.

At the same time, virus purification agents were launched between the fifth defense line and the base defense line to minimize the harm caused by the use of viruses by zombies.

The infectivity of the zombie virus is very terrifying. Even wearing protective clothing, there is still a certain chance of being infected, so I dare not be careless.

Looking at the strategy of the zombies, it seems that they want to use the zombie virus to assimilate humans into zombies.

The human soldiers in the fifth line of defense retreated, and Li Mochou's skeleton army had no choice but to retreat. Otherwise, it would be too far away from the base, and without the support of a human army behind them, it would be very dangerous to face the zombie army alone.

Before the skeleton army retreated, under Li Mochou's control, the magic circle was dismantled and the magic materials were transported back to the base.

After all, magic materials are scarce, and if you use them, you will use less, so you can't waste them, and bring all the usable ones back to the base.

The army of zombies successfully entered the fifth line of defense, and the fifth line of defense exploded instantly, wiping out all the zombies inside.

And because the crystal energy weapon is hidden in the fifth line of defense, when it explodes, the crystal energy weapon is activated, and the zombies within a radius of five kilometers are turned into fly ash.

After the fall of the fifth line of defense, only the last barrier remained, the last line of defense of the base.

Once the defense line of the base is captured, the zombies will directly attack the base, and the third military region will inevitably become a human base captured by the zombies.

All of a sudden, everyone's faces became serious, and a battle of survival was about to come.

The zombies had already attacked the defense line of the base, and the senior officials of the third military region in the operation room left the operation room one after another, and went to the front to personally command the battle.

Han Yuan and Li Mochou followed Ling Shuang to the east defense line where the zombies were most turbulent. Standing on the huge super alloy defense line, looking at the densely packed zombies in the distance, everyone's expressions became solemn.

The defense line of the base is the strongest line of defense, equipped with a hundred crystal energy weapons, countless warships of various types, and tens of thousands of combat intelligent robots.

A set of mechas also appeared on the defense line, the huge energy shields have been opened, and the muzzles on the defense line have also been opened.

Li Mochou commanded the army of skeletons, hiding in the magic circle, maintaining the operation of the magic circle, and making and devouring the skeletons.

The magic circle outside the base defense line does not have the ability to block zombies, but it can refine some zombies that pass through the magic circle into skeletons.

This can also be regarded as increasing the strength of oneself. Skeletons can be used to consume part of the zombies to a certain extent.

Xiaoku has reached the final stage of evolution. Li Mochou is not worried about whether she can withstand the attack of zombies. She is only worried about whether she can produce enough skeletons to help Xiaoku evolve.

The mighty army rushed over, passed the magic circle, and continued to move towards the base defense line.

After passing through the magic circle, there will always be fewer zombies in the zombie team, and after coming out of the magic circle, the momentum will suddenly become weaker.

Zombies are constantly being turned into skeletons, and the little skeletons hide in the magic circle, constantly devouring the newly transformed skeletons, and constantly strengthening their own strength.
